In order to obtain the stem diameter,height,sweep and to accelerate the automatic measurement for trees,a automatic me- asurement system is developed based on digital image processing. The measurement system mainly consists of an image capturer, a viewing angle adjustor, two calibration rods and an adjustable vertical staff and a notebook PC computer.

This review discusses the international development status of biodiesel fuels in terms of 5 potential oil plants (Jatropha curcas, Cornus wilsoniana, Xanthoceras sorbifolia, Pistacia chinensis and Cerasus humilis) and 1 wild oil plant species mainly introduced according to the situation in China. The advantage of improving the content of oil plants by transgenic technology is discussed, and 4 techniques of biodiesel fuel production are summarized.

本文介绍了极具潜力的5种木本油料植物麻疯树、光皮树、文冠果、黄连木和欧李和1种野生草本油料植物海篷子，进而提出运用转基因技术提高燃料油植物种子含油量的优势，归纳总结了生产生物柴油的4种不同工艺。

The result of analyzing the base content revealed that only the sequences from Buxus bobinieri have GC bias, especially at the third base of codes, and the GC content is more than 70%. All of molecular phylogenetic trees, based on the Beyesian, MP, and NJ methods, consisted of three major clades. Four sequences from Ceratophyllum demersum were grouped into a monophyletic clade (subfamily Ⅱ). Two sequences out of Trochodendron aralioides nested in subfamily Ⅲ. Another three sequences from Kingdonia uniflora interspersed among different subclades of subfamily Ⅰ.

用贝叶斯法、最大简约法和邻接法构建的CHS基因的分子系统树均由3个主要分支构成，其中一个分支由来自金鱼藻的4个序列聚在一起构成了subfamily Ⅱ，来自昆栏树的2个序列聚在一起网接于subfamily Ⅲ中；来自独叶草的3个序列分散于同一亚家族(subfamily Ⅰ)的不同分支中；而多数种的序列分散在相距较远的两个分支中，构成了两个主要的亚家族subfamily Ⅰ、subfamily Ⅲ。

DNA sequence data of the rbcL gene, the matk gene, and the internal transcribed spacers of nuclear ribosomal DNA involving 14 species representing the Cercidiphyllaceae. Eupteleaceae. Platanaceae, Tetracentraceae. and all the subfamilies of the Hamamelidaceae have been investigated in the present study.

本研究测定了包括连香树科、领春木科、悬铃木科、水青树科和金缕梅科内所有亚科代表共计14个种的rbcL基因，matK基因和18S-26S核核糖体内转录间隔区的序列，并结合原有资料对所有低等金缕梅类及其相近类群进行了分支分析。

In order to analyze the airborne LiDAR data corresponding to single trees and stand heights in the forestry area, we set up samples to measure tree heights of Alnus formosana, Cryptomeria japonica, and Chamaecyparis formosensis in the Alishan area. We build the Canopy Height Model based on the data from the airborne laser scanning system. Single Tree heights were estimated by averaging the CHM values within a 0.5m radius, and six different sizes of sample stands (5×5, 10×10, 12.5×12.5, 15×15, 17.5×17.5, and 20×20) were set up to extract the average heights within the area as the calculated value.

本研究於阿里山地区设置样区，针对台湾赤杨、柳杉、红桧等树种进行立木树高之量测，配合该样区之空载光达影像资料，建立树冠高度模型(Canopy height model， CHM)，探讨空载LiDAR在森林地区对於单木树高与林分高的量测情形；单株立木高系以样区立木位置为中心，萃取0.5 m 圆形环框范围内之CHM平均值为其推估值；光达林分高则以6种林分面积(5 m×5 m、10 m×10 m、12.5 m×12.5 m、15 m×15 m、17.5 m×17.5 m、20 m×20 m)萃取范围内之CHM平均值为其推估值。

Purpose of the experiment was searching for the method of cutting reproduction of Elaeagnus mollis., providing a foundation for the clonic selection in the wild population, and offering sufficient quantity of clone stocks for studying the relation between growth and nitrogen—fixing root tubercle bacteria.

本试验的目的是研究翅果油树扦插繁殖方法，在其野生群体中进行无性系良种选育的效果，以及翅果油树生长与固氮根瘤菌之间的关系，为接种■氮根瘤菌提供足够数量的无性系苗木。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
